Estimating the spatial variability of soil properties is essential for soil and crop-specific management.
This study addressed the spatial variability of soil parameters viz., texture, drainage, soil pH, organic
carbon and electrical conductivity in Haryana using Inverse Distance Weighted (IDW) interpolation
method provided in Arc GIS 10.1 software. Results showed that 43.7% of the total area was characterized
by low availability of organic carbon (OC), whereas 53.3% area by medium availability and only 2.9% area
by high availability. Soil pH values indicated that 43.81% area was found moderately alkaline, whereas
55.83% area as slightly alkaline and 0.3% as neutral. The distribution of electrical conductivity (ECe)
showed that 98.3% area was non-saline and only 1.7% area was found slightly saline. It was also
observed that only 0.27% area was found under imperfectly drained soil.
